There is that speaketh like the piercings of {i} a sword: but the tongue of the wise is health.

(i) Which seek nothing more then to provoke others to anger.

Wesley's Notes

12:18 Health - Tends to the comfort and benefit of others.

Jamieson-Fausset-Brown Bible Commentary

18. speaketh-literally, "speaketh hastily," or indiscreetly (Ps 106:33), as an angry man retorts harsh and provoking invectives.

tongue . health-by soothing and gentle language.

Matthew Henry's Concise Commentary

12:16. A foolish man is soon angry, and is hasty in expressing it; he is ever in trouble and running into mischief. It is kindness to ourselves to make light of injuries and affronts, instead of making the worst of them. 17. It is good for all to dread and detest the sin of lying, and to be governed by honesty. 18. Whisperings and evil surmises, like a sword, separate those that have been dear to each other. The tongue of the wise is health, making all whole. 19. If truth be spoken, it will hold good; whoever may be disobliged, still it will keep its ground. 20. Deceit and falsehood bring terrors and perplexities. But those who consult the peace and happiness of others have joy in their own minds. 21. If men are sincerely righteous, the righteous God has engaged that no evil shall happen to them. But they that delight in mischief shall have enough of it. 22. Make conscience of truth, not only in words, but in actions. 23. Foolish men proclaim to all the folly and emptiness of their minds. 24. Those who will not take pains in an honest calling, living by tricks and dishonesty, are paltry and beggarly. 25. Care, fear, and sorrow, upon the spirits, deprive men of vigour in what is to be done, or courage in what is to be borne. A good word from God, applied by faith, makes the heart glad. 26. The righteous is abundant; though not in this world's goods, yet in the graces and comforts of the Spirit, which are the true riches. Evil men vainly flatter themselves that their ways are not wrong. 27. The slothful man makes no good use of the advantages Providence puts in his way, and has no comfort in them. The substance of a diligent man, though not great, does good to him and his family. He sees that God gives it to him in answer to prayer. 28. The way of religion is a straight, plain way; it is the way of righteousness. There is not only life at the end, but life in the way; all true comfort.

Matthew Henry's Whole Bible Commentary

Verse 18

The tongue is death or life, poison or medicine, as it is used. 1. There are words that are cutting and killing, that are like the piercings of a sword. Opprobrious words grieve the spirits of those to whom they are spoken, and cut them to the heart. Slanders, like a sword, wound the reputation of those of whom they are uttered, and perhaps incurably. Whisperings and evil surmises, like a sword, divide and cut asunder the bounds of love and friendship, and separate those that have been dearest to each other. 2. There are words that are curing and healing: The tongue of the wise is health, closing up those wounds which the backbiting tongue had given, making all whole again, restoring peace, and accommodating matters in variance and persuading to reconciliation. Wisdom will find out proper remedies against the mischiefs that are made by detraction and evil-speaking.
